Note supplied by Mr. Fox. 
“ At the first nine stations in this Table, a few fibres only of unspun silk were em- 
ployed for suspending the weights; but at the last five, a very fine silk thread was 
used for this purpose, which caused greater leverage on the grooved wheel, and con- 
sequently greater deflection of the needle, on which account it was found, after a 
series of comparative experiments, that *0060 should be added to the decimals ex- 
pressing the intensity, which has accordingly been done in the results entered in the 
Table.”
